Pipette tip handling device assembly



FIG. 1 shows an exploded perspective view of a pipette tip handlingdevice assembly of the present invention. From top to bottom, theindividual components are identified as an actuator housing, actuatorplate, pipette tips, distal barrier plate, alignment housing, andloading block. The ellipsis markings indicate the presence of a fullcomplement of pipette tips where the full complement of pipette tipswere omitted for clarity of illustration. The full complement of pipettetips, as shown in FIG. 2, form part of the claimed design;

FIG. 2 shows an exploded perspective view as seen in FIG. 1 of a pipettetip handling device assembly of the present invention with a fullcomplement of pipette tips added for illustrative purposes;

FIG. 3 shows an enlarged side elevation view of a pipette tip of thepipette tip handling device assembly shown separately for clarity ofillustration. Pipette tip(s) is/are shown in FIGS. 1, 2, 5-11, 15 and 16with partial views thereof in FIGS. 4, 13 and 14;

FIG. 4 illustrates a cross section of the pipette tip of FIG. 3 takenalong lines 4-4 or FIG. 3;

FIG. 5 shows a perspective view of an assembled pipette tip handlingdevice assembly of FIG. 1. The ellipsis markings indicate the presenceof a full complement of pipette tips where the full complement ofpipette tips were omitted for clarity of illustration. A full complementof pipette tips, as shown in FIG. 2, form part of the claimed design;

FIG. 6 is a cross sectional view taken along line 6-6 of the pipette tiphandling device assembly of FIG. 5. From top to bottom, the individualcomponents are identified as an actuator housing, actuator plate,pipette tips, distal barrier plate, alignment housing, and loadingblock. The ellipsis markings indicate the presence of a full complementof pipette tips where the full complement of pipette tips were omittedfor clarity of illustration. A full complement of pipette tips form partof the claimed design;

FIG. 7 is a cross sectional view taken along line 7-7 of the pipette tiphandling device assembly of FIG. 5 with a full complement of pipettetips added for clarity of illustration;

FIG. 8 shows the view of FIG. 7 after the actuator has been fullyactuated. From top to bottom, the individual components are identifiedas an actuator housing, actuator plate, distal barrier plate, alignmenthousing, and loading block comprising pipette tips. The ellipsismarkings indicate the presence of a full complement of pipette tipswhere the full complement of pipette tips were omitted for clarity ofillustration. A full complement of pipette tips form part of the claimeddesign. In the fully actuated state as shown, some ejected pipette tipshave been removed for clarity of illustration;

FIG. 9 shows a side elevation view of a pipette tip as shown in FIG. 3;

FIG. 10, taken from FIG. 7, shows an enlarged cross sectional view ofnested pipette tips of the pipette tip handling device assembly with thebottom pipette tip positioned for loading into the loading block;

FIG. 11, taken from FIG. 7, shows an enlarged cross sectional view ofnested pipette tips of the pipette tip handling device assembly showinga condition of use where the bottom pipette tip is fully inserted intothe loading block;

FIG. 12 is a perspective view of a loading block portion of a pipettetip handling device assembly shown separately for clarity ofillustration;

FIG. 13 shows a distal nozzle of a pipettor engaging a proximal port ofa pipette tip in a loading block portion of FIG. 12;

FIG. 14 shows multiple nozzles of an automated manifold engagingmultiple pipette tips in a loading block portion of FIG. 12;

FIG. 15 shows the cross sectional view of FIG. 6 with the addition of asecond alignment housing situated between the actuator housing and firstalignment housing. From top to bottom, the individual components areidentified as an actuator housing, actuator plate, pipette tips, firstalignment housing, pipette tips, distal barrier plate comprising pipettetips, second alignment housing, and loading block. The ellipsis markingindicates the presence of a full complement of pipette tips where thefull complement of pipette tips were omitted for clarity ofillustration. A full complement of pipette tips, as shown in FIG. 2,form part of the claimed design;

FIG. 16 shows the pipette tip dispensing device of FIG. 15 in a fullyactuated, compressed state. From top to bottom, the individualcomponents are identified as an actuator housing, actuator plate, firstalignment housing, distal barrier plate, second alignment housing, andloading block comprising pipette tips. The ellipsis marking indicatesthe presence of a full complement of pipette tips where the fullcomplement of pipette tips were omitted for clarity of illustration. Afull complement of pipette tips form part of the claimed design. In thefully actuated state as shown, some ejected pipette tips have beenremoved for clarity of illustration;

FIG. 17 shows a bottom perspective view of a distal barrier plateportion of a pipette tip handling device assembly;

FIG. 18 shows an enlarged cut away view of FIG. 17;

FIG. 19 shows a cross sectional view taken along line 19-19 of FIG. 17thereof;

FIG. 20 shows an enlarged cut away cross sectional view taken from FIG.20 of one channel;

FIG. 21 shows a bottom view of a distal barrier plate portion of apipette tip handling device assembly;

FIG. 22 shows an enlarged partial view of FIG. 21; and,

FIG. 23 shows a side view of the distal barrier plate, where the tailsare varied in length.

Broken lines, where utilized, are for illustrative purposes only, arenot part of the claimed invention, and do not limit the claimed designto the features shown in broken lines. The broken lines are included forthe purposes of illustrating unclaimed portions of the pipette tiphandling device assembly and form no part of the claimed design.

CLAIM The ornamental design for a pipette tip handling device assembly, as shown and described.
